In faith, share out money (4)
I believe the answer is:
cult
'in faith' is the definition.
'cult' can be an answer for 'faith' (cult is a kind of faith). I'm not certain of the 'in' bit.
'share out money' is the wordplay.
'share' becomes 'cut' (cut is a kind of share).
'out' indicates putting letters inside.
'money' becomes 'l' (L can mean 'pounds').
'cut' enclosing 'l' is 'CULT'.
Can you help me to learn more?
(Other definitions for cult that I've seen before include "Unorthodox or false religion" , "System of religious beliefs and rituals" , "Narrow or excessive devotion to person or religious system" , "Popular cause, fashion" , "Group with system of formal worship" .)
